Robust and efficient biometrics based password authentication scheme for telecare medicine information systems using...

Area of Science:

• Computer Science
• Information Security
• Biomedical Engineering

Background:

• Telecare Medicine Information Systems (TMISs) require robust authentication for remote patient access.
• Existing chaotic map-based authentication schemes for TMISs have demonstrated vulnerabilities.
• Li et al.'s recent scheme, while advanced, exhibits weaknesses in session key security and user impersonation resistance.

Purpose of the Study:

• To identify and address security flaws in Li et al.'s smart card-based authentication scheme for TMISs.
• To propose a novel, secure, and efficient authentication scheme for telecare environments.
• To enhance the overall security and practicality of remote healthcare access systems.

Main Methods:

• Analysis of security weaknesses in Li et al.'s authentication scheme.
• Development of a new authentication scheme integrating chaotic maps, smart cards, biometrics, and hash functions.
• Informal and formal security analyses to validate the proposed scheme's resilience.

Main Results:

• Li et al.'s scheme was found vulnerable to session key compromise and user impersonation.
• The proposed scheme effectively mitigates identified vulnerabilities, including those in Li et al.'s method.
• The new scheme demonstrates enhanced security and efficiency compared to prior authentication methods.

Conclusions:

• The proposed chaotic maps and smart cards based password authentication scheme offers a more secure and practical solution for telemedical environments.
• Biometrics and hash functions significantly improve the robustness of telecare authentication systems.
• The developed scheme provides resilience against known attacks, ensuring safer remote healthcare delivery.
